• Q: How to replace the Mass Air Flow Sensor/intake air temperature sensor on 2007 Cadillac DTS?

  A: The first step to replace Mass Air Flow Sensor requires disconnecting the engine harness electrical connector from the Mass Air Flow Sensor. The owner should first disconnect power from the Mass Air Flow Sensor before loosening duct clamps at the Throttle Body and the Mass Air Flow Sensor location and then remove the outlet duct. The Mass Air Flow Sensor must be extracted after removing its bolts. Handle the Mass Air Flow Sensor with care during installation because contact with sensing elements must be avoided and any solvent or lubricating substances need to remain away; however, a minimal amount of soap solution helps with installation. Screw down the Mass Air Flow Sensor with its retaining bolts until they reach 4 n.m (35 lb in) tightening value. Reinstall the air cleaner outlet duct after securing its clamp at the Mass Air Flow Sensor to 4 n.m (35 lb in) and at the Throttle Body to match the same torque setting. The last step is to plug in the engine harness electrical connector to the Mass Air Flow Sensor.
